In this search, we study the gravitational field engendered by a
material segment around itself. In the beginning, we discuss the
concept of the gravitational field generated by arbitrary curve. It turns out
that this field depends on the concept
of linear mass, and is directly relate to the distance of the position, to which we calculate the field from the tangents of curve, and not from the curve itself.
Material segment is a special case of material curves, and characterized by the confusability of all its tangents, that allow simplify the calculations, and find a simplified formula of the field. We end our research by comparing the field of material segment, with a field of appropriate circular arc.
Contrary to what it is expected, it appear in the end that the field of material segment is inversely proportional to the distance from that segment, and not to the square of distance
